FLINT — A three-team alliance from Grand Blanc, Auburn Hills and Lansing won the 2012 Kettering University FIRST Robotics District Competition Saturday in Flint.

Grand Blanc’s Team 2337, the Enginerds, joined with Auburn Hill’s Team 33, the Killer Bees, and Lansing’s rookie team, Star Trec, Team 4294, to take top competition honors during the district contest in Kettering’s Recreation Center.

Thirty-nine robotics teams competed at Kettering on March 2-3, one of 10 district robotics contests in Michigan this year. More than 3,000 visitors attended the two-day district competition — making it the single largest robotics event in Kettering history.

A number of other awards were presented during Kettering’s district games this weekend. The winners are:
